Thanks for pointing this out, it seems I missed these failures when
regenerating ulps for various platforms after moving catan/catanh tests to
the auto-libm-test machinery. I've reported this as an MPC bug
<https://lists.gforge.inria.fr/pipermail/mpc-discuss/2017-March/001404.html>.
Once fixed (i.e. test expectations regenerated with fixed MPC), recently
regenerated catan/catanh ulps should be deleted before regeneration so
that they can be reduced in the course of regeneration.
